Question 12.36: In the organic compound CH=CH–CH–CH–C≡CH, the pair of hydridised orbitals involved in the formation of: C – C bond is: (a) sp – sp (b) sp – sp (c) sp – sp (d) sp– sp
In the given organic compound, the carbon atoms numbered as 1, 2, 3, 4, 5, and 6 are sp, sp, sp, sp, sp, and sp hybridized respectively. Thus, the pair of hybridized orbitals involved in the formation of C-C bond is sp – sp.
